Abstract Motor Segerak Magnet Kekal (PMSM) menjadi semakin penting dalam pelbagai aplikasi-aplikasi industri kerana motor ini memiliki tork- inersia nisbah yang tinggi, ketumpatan kuasa yang bagus dan kecekapan yang tinggi. Tujuan utama yng hendak dicapai melalui projek termasuk memahami pembinaan dan operasi asas PMSM dan seterusnya mereka bentuk satu sistem pacuan kawalan vektor untuk PMSM dalam persekitaran MATLAB / Simulink 7. Proses pelaksanaan projek melibatkan penentuan spesifikasi reka bentuk sistem, pemodelan matematik bagi pacuan dan pembinaan sistem pacuan dengan menggunakan Simulink. Pemodelan matematik bagi bahagian-bahagian yang berbeza dalam sistem pacuan dibentangkan secara terperinci. Langkah-langkah bagi pelaksanaan sistem pacuan dalam Simulink dipamerkan untuk menjelaskan proses penukaran model-model matematik pacuan kepada subsistem-subsistem. Sambutan dinamik yang cepat bagi sistem pacuan dibuktikan melalui keputusan simulasi dengan peralihan kelajuan yang lancar dari satu keadaan mantap kepada yang lain di bawah pengaruh perubahan langkah seketika dalam tork elektromagnetik. Jumlah herotan harmonik (THD) dan spektrum harmonik gelombang sinusoid arus motor dianalisis dan didapati kurang daripada 5% dan mematuhi tahap IEEE 519-1992. Sistem pacuan selanjutnya boleh diperbaiki dengan strategi-strategi kawalan tambahan yang lain atau pendekatan-pendekatan berbeza untuk kawalan vektor PMSM pada masa akan datang _________________________________________________________________________________________ Permanent Magnet Synchronous Motor (PMSM) is becoming quite significant in various industrial applications for its high torque-to-inertia ratio, superior power density and high efficiency. The main goals to be achieved in this project is to understand the construction and operation of the PMSM as well as to develop a high performance vector –controlled drive system for PMSM in MATLAB/ Simulink environment. The process of implementation involves the design specifications, mathematical modeling of the drive and Simulink implementation of the drive system. A detail mathematical modeling of the drive for different drive components is presented. The steps of Simulink implementation are outlined in order to explain the process of converting mathematical models of drive into subsystems. The fast dynamic response of the drive system is shown in the simulation results with smooth transitions of speed from one steady state to another under the influence of instantaneous step changes in electromagnetic torque. The total harmonic distortion and harmonic spectrum of motor sinusoidal current waveform is being analyzed and is found to be less than 5% in compliance with the IEEE 519-1992 standards for harmonics in power system. The drive system can be further improved with the additional control strategies or different approaches for vector control of the PMSM in the future.
